Answer:
All options are correct
Explanation:
Fossils are the remains of organisms (animals and plants) preserved in a rock. Scientists (geologists & palaebiologists) have used fossils to study the diversity of organisms in the past. This is based on their preserved morphological features. For example, several species of foraminifera has been identified in the rocks. Among them, some species are present today whereas others have become extinct.
Similarly, fossils are the indicators of past climate (e.g. temperature) as well. This means, if a specific species can survive at a particular temperature, its presence suggest that particular environment. For example, corals survive in tropical waters at specific depth and sunlight. So, if we find corals fossils, the cliamte of that particular age would be roughly the similar.
In the end, fossils can also provide evidence of orogeny (mountain building) process. These are typically plants fossils which cannot move and their remains are preserved in the folding rocks.
Answer:
1 = A
2 = B
3 = B
Explanation:
1) Black holes occur when really big stars collapse on themselves. And, in order to get big, the star has to be an old one.
2) A black hole is something huge that swallows up everything, while a protostar is just the very beginning of a star.
3) Scientist can't truly know for sure, but they can infer about them due to the effects of the surrounding areas.
The biome that has over 100 inches of rain each year is the Rainforest. Therefore, the Rainforest has abundant rainfall.
